Sleep, consciousness, as well as symbolizing time and space trait, can be described as a dual temporal state, and therefore a state of unconsciousness. In the process of this unconscious, there is no question of a state of action arising from a subject-object relation. The uncontrollable actions and reflections of the subconscious gain a supernatural dimension through sleep, which constitutes a platform for informality, that is, an erosion process. The selfs and actions that are repressed by memories in the individual memory or by collective consciousness are references to the integrity of actions and pleasures peculiar to this platform. Because the subconscious moves with emotions, not with analytical conclusions. This mysterious quality of sleep, which is a hypnotic process that we can understand as a kind of space and time, is the preference of verbal products based on narrative principals, especially mythic narrations, as a transition metaphor among the multi-layered events chain or as one of the methods of epic existence the main reason. In some cases, the state of unconsciousness caused by sleep may also be the starting point of epic adventures. The basic proposal for aphorism is "a sleep in life, a wake in death." The unconscious and timeless journey that begins with sleep is the source of truth. Sleeping giants, beauty, heroes, creatures; sleeping places and times are in the world of epic narratives in the world of universal consciousness. As an element of universal consciousness in this framework, the phenomenon of sleep takes on the function of being the founding element of the narrative from a motif in epic accounts. In epic species based on the narrative basis of the Turkish epic epic tradition, sleep manifests itself as one of the most important founding documents of the epic struggle that provides the epic existence of the central hero. The main characteristic of the conflicts that start with sleep is that the hero is taken captive while sleeping with the epic hero's invincibility, or the involuntary elements are included in the narrative while he is asleep. In the context of the Turkish epic tradition, "deaf sleep, alpine sleep, or Ogus sleep" are concepts that arise in this frame. In this study, there is a lot of sleep on the phenomenon of dream which is done in many studies, and this process will focus on the functions of epic narrations.
